RIGID AVERAGING

Continuous Averaging, Transmitter

The ACI Transmitter Rigid Averaging Series features a two-wire, 4 to 20 mA loop powered
output signal with an optional 3-Wire voltage output signal available. The Rigid Averaging
sensors are designed to be installed in small to medium size ducts to give you a better average
compared to that of a single point sensor. All transmitters include Zero and Span adjustments
for eld calibration and are calibrated using NIST Certied Calibration equipment. ACI
recommends the use of an 18 to 22 AWG shielded cable for all temperature transmitter
installations to help eliminate the possibility of noise being introduced onto the signal lines.
The 1K Ohm Rigid Averaging sensor assemblies include a continuous sensing element the
covers the entire length of the stainless steel probe and are manufactured using colored
Etched Teon lead wires to dierentiate between the dierent sensor types. All units are
hermetically sealed using our epoxy material to eliminate the eects of moisture on the

limit vibration once installed. Optional NEMA/IP rated weather proof enclosures are available as specied on the back of the product data sheet.
For best accuracy, ACI recommends the use of the A/TTM Series Matched transmitters with a 3 or 5 Point NIST Calibration Certicate, since they
include a second calibration process in which the RTD and transmitter are calibrated together as a system. On larger ducts, our bendable copper
averaging transmitter should be used for better coverage and control of the air inside of the duct.

Applications: Roof Top Units, Air Handlers, Monitoring Supply/Discharge/Return/Mixed Air Temperatures, Data Centers, Hospitals

sensors. The Rigid Averaging transmitters include a foam pad to properly seal the duct and
